By the end of December 2020, there were at least 123 wolves in nine packs that lived primarily in Yellowstone National Park. Packs tend to have an average of around 9.8 wolves, with the largest pack ever recorded in Yellowstone containing 37 wolves (the Druid Pack, recorded in 2001).
If you’re hoping to experience Yellowstone National Park with significantly less crowds, the winter might be a great time for you to visit. While most of the roads and facilities are closed during the colder months, some lodging stays open, and guests can take advantage of snowmobile or snowcoach tours. Quiet and near-private experiences with wildlife, like the wolf encounter below, or much more likely when the park is less crowded.
As with any wildlife in Yellowstone National Park, wolves always need to be given plenty of space. For both wolves and bears, this means at least 100 yards (300 feet). Wolves are not usually a threat to people and will typically keep their distance. In fact, there’s never been a reported case of a wolf attacking in human in Yellowstone.

Yellowstone National Park Wolf Safety Guidelines:
Wolves are not normally a danger to people, unless they become habituated to their presence and food (there has never been an attack in Yellowstone). Two habituated wolves have been killed in the park. Help us protect wolves in Yellowstone by:
- Remaining at least 100 yards away when watching or photographing them.
- Telling a ranger if you see wolves near developed areas or approaching people.
- Keeping your dog leashed at all times when it’s outside a vehicle.
If you’re concerned about a wolf because it’s too close or not showing any fear of people, stand tall and hold your ground. If the wolf approaches you, wave your arms, yell, and flare your jacket. If that doesn’t discourage it, throw something at it or use bear spray. Group up with other people, continue waving and yelling, and tell a ranger as soon as possible.
Do not handle wolf scat: it may contain tapeworm eggs that can cause hydatid disease in humans.
